27: Problems at a California securities firm rippled through the penny-stock market, forcing at least one Florida brokerage firm to stop trading, and it sent the shares of several small companies tumbling.
A: forcing at least one Florida brokerage firm to stop trading, and it sent
B: forcing at least one Florida brokerage firm to stop trading and sending
C: forced at least one Florida brokerage firm to stop trading and sending
D: with at least one Florida brokerage firm forced to stop trading and sending
E: at least one Florida brokerage firm was forced to stop trading, and it sent
搜索了一下，以前没问过。
答案是B。但我觉得B有歧义，因为sending 可以和trading并列也可以和forcing并列。
我选的D,请问D哪错了？
谢谢！马上考了。 |
